main features
1. Intelligent host, which adopts a high-speed and high-performance digital signal processor with fast operation speed and wide transmission frequency band. It can generate a high-density fitted sine wave of 360 points per cycle for the fundamental wave. This is currently at a higher level among similar output methods. Due to the large number of points, the fidelity of the waveform is high, and the distortion is small, especially during harmonic output, even for 9th harmonic and 300Hz, it can achieve a high density of 60 points per cycle.
2. Single machine independent operation, the device operates through a large screen touch LCD display screen, displaying in Chinese. It can complete most of the on-site testing and verification work, and can verify various relays (such as current, voltage, inverse time, power direction, impedance, differential, low cycle, synchronization, frequency, DC, intermediate, time, etc.) and microcomputer protection. It can also simulate various complex instantaneous, permanent, and conversion faults for whole group testing.
3. By connecting computers and using Chinese operating software on the Windows platform, various large-scale, complex, and more automated verification tasks can be carried out. It is convenient to test and scan various protection settings, store test data in real-time, display vector maps, draw fault waveforms, and print reports online. 4.16 bit DAC chip with 16 bit high resolution ensures high waveform fitting accuracy and good linearity. Small signal output also ensures small distortion.
5. New type of high fidelity power amplifier, with a new high-power modular high fidelity power amplifier component used in the output stage, which can be used for both current and voltage output. The output power is high, and each phase voltage can output up to AC100V/130V (xN), with current triple output up to AC90A (xN-30A)/120A (xN-40A)/180A (xN-60A). Good accuracy and high reliability.
6. Direct output of phase voltage and phase current using DC power amplifier output method, which can directly output AC voltage, AC current, DC voltage, DC current, and variable angle and frequency, and can add 0-9 harmonics.
7. Self protection, adopting a reasonably designed heat dissipation structure, with reliable and comprehensive multiple protection measures, power soft start, and certain fault self-diagnosis and locking functions.
8. Rich contacts, with 10 contact inputs and 6 empty contact outputs. The input contact is compatible with the null contact and the 0-250V potential contact, which can be intelligently and automatically recognized.
